They are designed to imitate the movements of a normal disc, but they do not have the shock absorbing properties of a healthy disc. This new disc can only be placed via the abdomen. This technique can be applied to both cervical and lumbar vertebrae.

These images show the purpose of the procedure. A mobile prosthesis is placed at the location of the diseased disc between the fifth lumbar vertebra and the sacrum.

Discus Prothese 3

The disc itself consists of two titanium plates linked by a central ball joint.

Discus Prothese 4

These "artificial discs" are available in different sizes for different patients.

The results of these studies are presented at international conferences and published in medical journals (see scientific contributions).

The theoretical advantage of this technique is that a moving segment (a 'natural' joint) is replaced by another joint, even though man-made. Thus mobility remains optimal and the adjacent intervertebral discs are relieved from additional stress.

The disadvantage is that there is still insufficient scientific evidence to enable doctors to consider this technique as being the unquestionably best option for treatment of a diseased intervertebral disc. Another disadvantage is the cost of the procedure (€ 2500), which is not reimbursed by Belgian mandatory health insurance.
